IMPROVEMENT IN COMPOSITIONS FOR DRESSING LEATHER.

Specification forming part of Letters Patent No. 12,171, dated January2, 1855.

To all whom it may concern Be it known that I, UUNO WVERNER, of the cityand county of Philadelphia, in the State of Pennsylvania, have inventeda new and useful Combination of Matter to be used in Dressing Leather 5and I do hereby declare that the following is a full, clear, and exactdescription thereof.

The nature of my invention consists in the employment of a new compoundto be applied to leather, afteritis tanned and dried, in place oftanuers oil and tallow, which are generally used, for the purpose ofrendering it more flexible and merchantable.

To enable others to make and use my invention, I give the followingdescription of the compound I use:

I take sixty pounds of a saturated infusion of oak-bark, or othersubstances from which tannin is generally extracted. To this I add fortypounds of common train-oil and thoroughly incorporate the mixture bystirring and agitating it until it acquires the consistency of thickcream. rosin, previously melted and incorporated with four pounds ofhogs lard, and, finally, I mix with the above one ounce of creosote topreserve the compound from molding. The above proportions are those Ifind best in practice 5 but they may be slightly varied.

The invention is especially applicable to the dressing or dubbing ofcalf-skins for boots and Ithen add sixteen pounds of" shoes, or what isgenerally called upperleather. To the composition of oil and tallowwhich is generally used my compound presents many advantages: first, onthe ground of matter more readily and with less labor.- The lard is usedto facilitate the melting of the rosin, and the creosote preserves itfrom mold.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The use or employment of a compound for dressing leather, composed of asaturated in fusion of oak-bark, (or other substances affording tannin,)train or fish oil, rosin, hogs lard, and creosote, compounded andcombined as herein set forth, and for the purposes specified.

In testimony whereof I have hereunto signed my name this 9th day ofNovember, 1854.
